To all whom tm/ay concern:

Be it known that I, GEORGE DAYTON,

a citizen of the United States, residinga'sat tom 4 and a drain King City, in the county of .Monterey and State of California, have invented certain,

new and useful Improvements in Acetylene- Gas Generators, oi which the following is a specication. A'

My invention relates to acetylene gas generators in which the carbid is contained in. a receptacle over the generator tank and has for one of its objects the provision ofm'eans by which the feed of the carbid into lthe generator tank is controlled by mechanism outside of the generator tank so as to prevent rust of the parts.

Another object of my invention is the provision of means for emptyingthe generator of the Water and sediment from the exhausted carbid without destroying the water seal,

and for emptying the generator of air beforel replenishing the storage' tank after'the flow has been out off to clean the generator.

Another object of my invention is such a construction of the storage tank and connections with the vcarbid feed in the generator that the ilow of gas to the burners is not stopped during the time the generator is being cleaned and a fresh supply of the carbid placed in the holder.

. The construction, operation and advantages of my invention will be fully explained hereinafter and illustrated in the accompanying drawings in which Figure 1 is a sectional elevation' of my improved acetylene gas generator and storage tank, and Fig. 2, a

of the generator.

In the drawings similar reference .characters indicate corresponding parts throughout -the severa-l views.

l represents the lowerA portion of my i mproved generator consisting of a cylindrical receptacle having two concentric walls 2 and 3 spaced apart and a centrally depressed b otpipe 5 secured-in a hole therein the outer end ofsaid drain pipe being provided with a faucet 'similar to the faucet ordinarily used'for syrups and molasses, i. e. with a swinging ate. said pipe 5 in which is secured a'vertical pipe 8 lhaving a funnel 9 at its'upperend and a valve 10 just belowsaid-unnel, saidpipeand funnel being intended to be used lin filling the receptaclel. f1

11 represents the upper portion'of the`l gen'- vertical sectional view' 7 represents a T in '.Water is' poured into the space erator'having .a cylindrical'wall 12 which itsy between the two walls 2 and between the walls as shown in the drawings serves to form a water seal to prevent escape of gas from. the generator. Above the Wall 12 the part 11 is formed frustumeshaped as shown at 13-andA then cylindrical at the top as shown at 14.' 0n the inside of cylindrical portion 14'is`se- 3 and when cured an inverted conershaped ho per 15 forming the bottoma of the carbid ho Xder and having a central opening'l for the esca e of .the carbid, 17 being a valve-.for contro ling the ow of the carbid from the holder.

18 represents a standard secured to the'top of the' cylindrical portion 14 and- 19 a lever, fulcrumed thereon, to vone arm of Which-is pivotally secured a rod 20the lower end of which is secred to the valv g17. On the other arm oflever 19 is secured. a weight 21 to normally hold the valve 17 closed, said weight beingadjustable on said arm by means of a set screw 21a.

22 represents lower'portion ofthe gas storage tank and .23 the pressure'bell having a weight 24 on its topfor compressing the gas and driving it out through service pipe' 25. The bell 23 has ears 26 on its sides that ride on rods 27 secured to the lower portion 22 and serving as guides for said bell 23.

28 represents a guide frame secured to the upper ends of rods 27and 29 a rodsecured to the top of bell 23 and riding in guide 28;

30 represents a leverlfulcrumed on one of the rods 27 and having one arm connected by means of link 31 with i vhavin the weight 21 thereon while the other the arm of lever 19 'end o said lever 30 is forked as shown at 32:

to receive rod- 29.

33 represents a c'ollar secured to rod 29 and adapted to engage the tines or forked end 32.v

It will be understood from this construction that the weight 21 serves to hold the valve 17 closed when the storage tank isiilled roo withs gas but when the gas is withdrawn through feed pipe .25 so that the bell is'depressed the collar 33 engages the forked end 32 of lever 30, depressing it and raising the Weighted end of lever 19, opening valve 17 to permit the escape of the carbid from the hop- '4 per '15 into the generator, which contains water, and gas is generated. A

34 represents .a pipe for conveying :the gen erate gas romjthe generator' tothe storage tank 'aving 'a T 35fon. the end inside of the ITO- gezierato'r to prevent the dripping .from con! I densed moisture on the upper portion of the generator dropping into the pipe.

36 represents a trap at the lowest portion of the pipe 34 to drain the pi'peof' any moisture that. may be therein and prevent it from 4becoming clogged thereby.

37 represents a 'valve for controlling the How of gas through said pipe 34.

38 represents a plate secured to one arm of lever 39 fulcrul'ned in the bottom of the enerator and having,a eoneshaped protu erance on its bottomA to normally seat in the lend of drain pipe While to the other arm of.'

.. the lever is secured a rod 40 that extends .'tor.

thlou i pipe 41 to the outside of the generalThe purpose of said plate 38 being to agitato the Water in the generator when c lganing it so as to insure removing all the residuumincident to the generation of the I1.2 represents a pipe connectingfthe top part of the generator With pipe 41 and having a valve 43 to openand close said pipe. The purpose of this pipe is as follows: After the generator has been cleaned, as above described, i't is generally found that a quantity of air has been admitted thereto which it is desirable lto remove'before refilling the storage tank. The. valve 37 in the pipe 34 having been 'closed before cleaning the generator the valve 43 is opened when the generation of gas is recommenced and the air escapes through pipe 42, after which the valve 43 is,

closed the valve 37v opened and the gas ows into the storage tank.

44 represents a tank secured to service pipe 25 and containing sponge to filter the gas' be fore it goesto the burners.

Inl operation'when the enerator is bei-ng,r cleaned and refilledthe co 4lar 33 is loosened on rod 29 so as to permit-the4 bell 23 to be depressed more than normally. so that the feedmg of the gas through the service pipe 25 need not be interrupted. After cleaning the 'generator and'reflling` the carbid holder the valve 17 ymay beheld open by hand pressure on the lever 19 until the storage tank has Vbeen refilled and the collar 33 is again secured to the rod 29 at the position desired thereon to properly regulate the iioW of carbid from the holder.

Having,r thus described my invention What I claim is- 1. In an acetylene gas generating and storing machine, a hopper for holding the carbid, arvalve to control the How ofy carbid from said hopper, a lever fulcrumed on top of the "generator, a rod connecting'one arm of said.

lever with the valve, a Weifrht adjustably mounted on the other arm o the lever, another lever suitably fulcruined having one arm connected with the Weighted arin of the first-mentioned lever' and the other arm forked, the storage tank ,having a Wei hted adjustable bell, arod secured to said bel andl adapted to reciprocate between the tines of the forked end of the lever, and a collar adjustably secured to said rod and adapted to engagel said tines, substantially as shown and described,

' said bell and adapted to reciprocatex between the tines of the forked end of the lever, and a collar adjustably secured to said rod and adapted to engage the tines when the adjustable bell lowers, substantially as shown and described.

In testimony whereof I hereto affix my si g `nature in the presence of two witnesses:

GEORGE -W. DAYTON. Witnesses: v 4 JOHN C. ToMrKrNs, JosIAH W. OoAN.
